Description
You’re in the timber, the late-season sun filtering through bare branches. A gobbler sounds off just out of sight, and you need a shotgun that swings fast, shoulders naturally, and is ready when you are. That’s the scenario where the Mossberg 500 Pump 20 Ga 20″ 3″ Mossy Oak Obsession Synthetic Adjustabl proves its worth. It’s a purpose-built, lightweight hunting shotgun designed for maneuverability in tight cover and quick shots in the field.
The Mossberg 500 Pump 20 Ga 20″ 3″ Mossy Oak Obsession Synthetic Adjustabl is a 20-gauge pump-action shotgun featuring a 20-inch vent-rib barrel, a 3-inch chamber, and Mossy Oak Obsession camouflage on a synthetic stock with an adjustable comb. Priced at $568.69, it’s a dedicated, ergonomic tool for turkey and small game hunters who value stealth and a custom fit. This configuration is drop-in ready for the woods, requiring no modification to be effective straight from the case.
Let’s talk about that adjustable comb. This isn’t just a comfort feature—it’s an accuracy upgrade. You can fine-tune the stock’s cheek weld to perfectly align your eye with the bead sight, which is critical for consistent point-of-impact with various turkey loads. When it comes to patterning a heavy #5 shot at 40 yards, that precise fit makes all the difference between a clean harvest and a missed opportunity. The synthetic stock is impervious to the elements, and the Mossy Oak Obsession pattern breaks up your outline against the varied browns and grays of late-winter and early-spring foliage.
The 20-inch barrel is the key to this shotgun’s agility. It provides a full-length sighting plane with the vent rib but keeps the overall length compact for navigating brush piles, blind doors, and thickets without snagging. Chambered for 3-inch shells, it gives you the flexibility to run everything from light target loads for squirrels to high-velocity turkey loads with dense patterns. The twin action bars on the pump ensure smooth, reliable cycling when you need a fast follow-up shot. Weighing in at approximately 6.75 pounds, it’s easy to carry all day and quick to mount.
Mossberg’s proven pump action is famously rugged, with a steel-to-steel lockup and a tang-mounted safety that’s intuitive to use with your thumb. The 20-gauge platform offers significantly less recoil than a 12-gauge, which means you can practice more and shoot more effectively in the field. This model is compatible with a wide range of Mossberg 500 20-gauge barrels and accessories, allowing you to configure it for other roles if needed. It ships with a factory-installed, extra-full turkey choke tube to tighten your pattern right out of the box.

Frequently Asked Questions
Q: Is the adjustable comb easy to modify in the field?
A: Yes. The comb height is adjusted using an included hex key. You can set it at home based on your preferred ammunition and optic (if adding a red dot), and it will stay securely locked in place. It’s designed for a one-time, personalized setup.
Q: Can this shotgun be used for home defense with the right ammunition?
A: While its primary design is for hunting, the 20-gauge platform with appropriate buckshot or defensive slug loads is a viable option for home defense. The shorter 20-inch barrel offers good maneuverability indoors. That said, you would likely want to change the extra-full turkey choke to a cylinder or improved cylinder bore.
Q: What is the capacity, and are extended magazine tubes available?
A: The factory capacity is 5+1 rounds. The Mossberg 500 uses a magazine tube that is integral to the barrel length. To change capacity, you would need to swap the entire barrel assembly for one with a different magazine tube length. Many aftermarket barrels and magazine extensions from brands like Carlson’s or S&J Hardware are compatible.
